Short barrel rifle project suggestions and help

I've finally decided after years of shooting that what my collection really needs is a short barrel rifle.

I decided this after coming down with a health problem that won't let me shoot my shotguns or any stout recoiling rifles anymore. I still want to shoot and thought that a lightweight, low recoiling, sub gun might be fun.

As a platform I've decided that I'm probably going to use an MPA 30 9mm

Seen here https://www.masterpiecearms.com/proddetail.php?prod=MPA30T

I chose the MPA 30 for the following reasons.

9mm is cheap
The MPA 30 is cheap but reliable from what I hear
9mm is quiet compared to rifle rounds from a short barrel
low recoil
Overall handiness

After I file all the paper work and get my tax stamp I will most likely get and adapter that will allow me to attach an AR-15 style collapsible stock and maybe a forward grip of some kind.

I think this is the cheapest way for me to enter the short barreled rifle world but am open to suggestions of other rifles that might be fun to short barrel.

I would even be open to thoughts on 9mm carbines that I wouldn't have to short barrel but that are within the $500 range as that is my budget limit.

If you already have an AR you can get just the upper for under $500. That's assuming that the $500 budget doesn't include the stamp.

I do.

But the issue with a short barrel AR is noise. I had a 7" AR-15 pistol once that I was planning to register but it was so loud that I routinely got asked to stop shooting it at the ranges I attended.

That's why I'm leaning towards something in a pistol caliber.

Understandable. I've gotten some dirty looks from my 11.5" before. I haven't priced kits, but you may be able to do a 9mm AR upper for under 500. The only pistol caliber carbine I have is a Marlin Camp 9. You might be able to get into one for under $500 including the stamp if you're lucky enough to find one in excellent shape for $175 like I did :) I used to have an MPA upper for my M11/9 but I never used it since I had a Lage upper as well. You're right about one thing - they are very, very handy indoors.

You can buy a 9mm AR short barreled upper, add about $100 the mag block and you'll be good to go after you get your stamp.

I've got the MPA mini side cocker and its fun to blast away with using a cheap red dot on the rail, but the trigger and grip are not conducive for comfortable shooting sessions.

I certainly agree every collection needs at least one SBR and supressor :).

I WISH I could have a suppressor. Minnesota state law says that's a no no.

Bumping this. I'm still looking for information on how to get into SBRs for cheap.

I like the 9mm upper personally. Cheap ammunition, easy to load subsonic if you handload.

300 blackout is fun and you can get by with just swapping the barrel out on a carbine. I am waiting on the paperwork for my 10 incher right now.

Both are very quiet suppressed, but since that may not be an option, I would give the advantage to the 9mm simply on cost of ammunition.

Does .300 blackout just use STANAG mags? I didn't know that.

Kel Tec Sub 2000. Not as cool as an SBR but for a fun gun 9mm carbine it fits the bill and should be well under $500.

Fitting in a standard AR mag is 300 BLK's whole raison d'etre.

A Sub 2k would is high on my list but I really want to get into the SBR game.

I converted a Draco pistol not long ago. It was a lot of fun and can be done relatively inexpensively depending upon how you want to trick it out. It started as just a fun gun project for me but turned out to be an awesome rifle in the end.

How much did it end up costing you to build?

I made an SBR AK for about $650. I have $100 in a Romanian kit (bought it a while back), $100 for a NoDak receiver, about $150 paid to have the barrel and gas system cut down to 9.5 inches, $200 for the tax stamp, $30 for a Tapco FCG, and $50 for a Chinese air rifle with a military sidefolding stock that I liked. I already had the tools to do the build, which helps the price.

That pictured draco isn't going to be real cheap in that it has ultimak handguard and gas tube ($300ish), CTR stock and riser ($100+), hinge and buffer tube ($100ish). Of course you have $200 in tax. Dracos used to sell for $350 or so but seem to be in short supply at the moment and thus are commanding higher prices right now.

One could do a less fancy draco SBR for much less. The cheapest easiest route would be to simply drill and and tap the back plate and add a $60 ace stock.

Dane17, any reason you have the aimpoint sitting so high?

That would be in 7.62x39 wouldn't it. That would be quite the fireball out of that short barrel!

I have a 7" 9mm RRA upper and a 10.5" 7.62x25mm CCMG upper. Both are fun shooters, but the 7.62x25mm is my hands down favorite.

Yes they are x39s (although there is also the champion chambered in 5.56). With a flash hider it is not that bad. Now the mini draco, with its 7.5" barrel on the other hand has a very serious fireball. I want to see if I can get it down to a manageable level with a smith vortex.

I've got an ~$15 US made Krinkov brake on mine Mini Draco while waiting for the stamp, its really no worse than a 6" 44Mag with full house 240 gr loads. The knock-off brake really does keep the muzzle down, much less than afore mentioned .44Mag off sandbags.

wally...where did you get your brake?

've got an ~$15 US made Krinkov brake on mine Mini Draco

Have you fired it at night? Firing the mini Draco at night with an A2 produced a flash that was literally momentarily blinding. An aimed follow up shot was not immediately possible. For a range toy that is just fine. For a defensive weapon it is not acceptable. I'v not fired a 44 mag at night so I do not know if that is the same.

Muzzle brakes and flash suppressors address different problems. My "fake" Kinkov brake came from either Cope's or Centerfire Systems, sorry I don't remember which for sure.

Its very effective at reducing muzzle rise and somewhat effective at reducing flash -- without it you can easily see the Mini Draco muzzle flash in daylight, a quite impressive fireball :)

These are always fun if your looking for an idea. ;)
